A Douglas man charged in connection with his wife's fatal jump from a second-floor window in their home earlier this year asked a judge today to dismiss the manslaughter charge against him and to suppress evidence in his case.

Allen M. Stilkey, 41, is awaiting trial in Worcester Superior Court on charges of manslaughter, threatening and steroid possession after a police investigation into the Feb. 10 death of 44-year-old Lisa Stilkey from injuries authorities said she suffered when she jumped from a second-story window at the couple's home at 38 Gilboa St., Douglas.

Police and prosecutors said the husband and wife had been fighting on the night in question and that Mr. Stilkey, a former national arm-wrestling champion, threatened to kill her before her fatal plunge.

A hearing was held today on motions filed by Mr. Stilkey's lawyer, Michael S. Hussey, seeking the dismissal of the manslaughter charge and the suppression of evidence recovered by police. Mr. Stilkey's trial has been scheduled for Dec. 3.

Judge James R. Lemire took the motions under advisement and gave Mr. Hussey and Assistant District Attorney Brett F. Dillon until Oct. 17 to file supplemental briefs.

Mr. Hussey maintains that the manslaughter charge against Mr. Stilkey should be dismissed because the evidence presented to the grand jury that indicted him was insufficient, as a matter of law, to sustain the charge. Mr. Dillon disputes that contention.

Mr. Hussey is seeking the suppression of evidence recovered by police inside the couple's home, as well as statements attributed to his client.

He alleges that police placed Mr. Stilkey in protective custody without legal justification and then conducted an unlawful protective sweep of the house. Observations made by police during the sweep were later used in an affidavit in support of their application for a search warrant.

Mr. Dillon maintains the protective sweep of the house to determine whether anyone else was inside was proper and that there was ample probable cause for the issuance of the search warrant even without the observations made during the sweep.

Douglas Police Officer Anthony Yannino, the first officer to arrive at the scene after Mr. Stilkey called 911, testified that he found Mrs. Stilkey on the ground beneath an open second-story window with blood coming from her mouth.

“She stated, 'I need the police,' " Officer Yannino said. He said the injured woman told him she jumped from the window after he identified himself as a police officer.

Mr. and Mrs. Stilkey both smelled of alcohol, according to Officer Yannino.

When asked what had happened, Mr. Stilkey related that he and his wife had been arguing, the officer testified. He said Mr. Stilkey, who appeared to be intoxicated, had a scratch on his left cheek.

When asked if he had been drinking, Mr. Stilkey responded, “Not as much as her,” according to Officer Yannino. The officer said Mr. Stilkey declined when he asked permission to look around inside the house “to rule out foul play.”

He said he placed Mr. Stilkey in protective custody and took him to the Douglas police station, where a breath test showed he had a blood-alcohol level of 0.07 percent.

Officer David Brown testified that he and other officers decided to break into the house to check for children or other occupants after peering through a window and seeing broken glass and a spilled liquid in the kitchen.

He said the officers exited the house after determining no one else was inside. State police detectives later arrived and a warrant was obtained to search the house, according to Officer Brown.
